Choose a place for construction of the freezer. It is best to equip it in the yard or garden. Provide direct entrance to the store or make a hole under floors of outbuildings. The size of the freezer select based on the needs in food storage. If your garden land is small, it makes no sense to have a massive storage industrial scale.
Basis camera will be a recess dug in the ground. Make a hole of such size that it was two feet deeper than the future of the camera and a meter larger in width and length. If you are planning to organize in the freezer dirt floor, to increase the depth required.
Now move on to production design for the refrigeration substance, which will be kerosene. From metal pipes with a diameter of 90-110 mm manufacture capacity in the form of a frame. The size and shape of the frame will determine the size of the bottom of the camera. The pipe design should be placed at a distance of 100-200 mm from the walls of the pit. In the middle of the design weld the two riser tubes of the same diameter. The height of these vertical pipes shall be such that after sealing the chamber with soil, the pipe ends protrude above the surface at 250-300 mm.
Around the perimeter of the excavated pit pitch of the formwork boards that fit the camera. Fill the formwork with concrete mortar, making the wall thickness equal to about 400-500 mm., These walls will provide good preservation of low temperature in storage.
Fabricate a door unit. The design of the doors is determined primarily by the location of the entrance to the freezer. If there is an entrance from the top, make the door of the hatch with a double lid, arranged between the two parts of the cover insulation foam. The chamber roof insulated and covered with slag.
Made of tube capacity pour the kerosene. On the upper ends of vertically standing tubes slip covers from a dense material (like foam). In winter, these covers should be removed. This freezer will allow you effortlessly to provide storage of a variety of food products, protecting them from damage.
